§1

Four questions. Every headline.

The same research process, applied the same way every time. It is what the book series teaches — and what the morning issue applies to the day’s news.

Q.01 → SOURCE

What happened, and which source supports the announcement?

Q.02 → CHANGE

What changed for the company, and how significant could that change be?

Q.03 → EXPECTATION

What was already expected or reflected in the market narrative?

Q.04 → UNCERTAINTY

What remains uncertain, and what additional evidence could change the interpretation?

§4

Built to be checked.

Sources cited

Every catalyst points back to the announcement it came from, so you can read the original yourself.

Rationale shown

A score is never just a number. Each one ships with the reasoning behind it, and a higher score is never a buy signal.

Uncertainty stated

Each issue names the evidence that could change the interpretation, before you act on anything.
